Trapped key systems use a series of mechanical locks and keys to control the access of gates or doors to running equipment or machines, ensuring safe access. Keys are trapped and released in a sequential order. Sets are available with a main station and from one to five gate switch modules, with optional solenoid locking models for maximum protection.

Trapped
Key Interlock System - SX and ZRH Series Dold Safemaster
Trapped Key System Gate Sets provide a full trapped key safety
system, in one- to five-gate sets. They are available in either
standard (SX) or solenoid-locking (ZRH) versions. All keys and
their corresponding 01 and 10 modules are identical within a set,
but unique to any other set. Also available are tongue key
actuators (purchased separately from the gate sets), and optional
items such as door actuators, captive safety key sets, key modules
for key exchange box setup, and mounting plates.

Trapped
Key Accessories The following optional actuator key sets
can be used with any of the Safemaster trapped key gate sets:

 1001-KEYMODULE-SET modifies an
SX-GATE-SET or a ZRH-GATE-SET to implement a key exchange box.
Uniquely keyed within itself, this set allows for expansion of a
key exchange plan.

 PADLOCKMODULE-SET adds a personal
safety feature for protection against being locked into a gate. One
or more personal padlocks can be applied to the module. While a
padlock is fixed to the module, the system cannot be restarted.

 ACTUATOR-SET-B is a gate actuator.
It can be added anywhere a gate function is required, so that the
SX or ZRH module can be used to protect or to lock a gate.

 01-SAFETY-KEY-SET adds a personal
safety key as protection against being locked into any module of an
SX or ZRH gate set. This key is normally trapped; when released the
operator can take it while in the machine.
